Be it known that 1. Mini: C. Loizii'rnniionz, a citizen of tho l'nitcdStates. and a resident of Noble. in the count)l of Cleveland and 5 Stateot (llilalioiiia. have invented certain new and useful improvements inMixers. ot'

which the following is ii bpecification.

Thin` invention relates to a mixer or va poriziing device adapted foruse in i'onnei-Y 1o tion with internal combustion cugini, :ind

an object of thc invention is to provide a mixer, which is placedbetween thi` cai'- lnireter and intiilic manifold of an ordinariinternal combustion engine. for siippliingI i5 and mixing hcatid airwith the com iiistililc ,iras prior to the entrance ot' this gas intothe cylinder of thc engine. to croate a conihnstihlc gas ot' higherellicicniv and Consequently result in thi creation of niiiXiniiini powerupon the utilization of a niiniA innni quantity ol gaseous l'iicl.

'A further ohji-i-tV ot the invention is to prorido a niixer. aSspecified. wli'iili has vali'ed connection with llii` ixhaiist iii-.iniYfold ot' the engine for supplying licatiid air to the ilianiliii' of theinixir, at which point thi' l. ated air will la' thoroiig'lil)v niixedwith lii i'oinlniatihiix gi or l'iicl lroni the ciolnireter. prioi' tothil deliver;- ol' thc t'uirl to thil cugino cylinder and |"iii'tlii-i'to provide an inria-ted U trap in thi pipi at itl i'creiring i-oil toforni an oh tructioii for lino p-.ii'iii-lil` of carhon in oiliiirforeign aciuninlation.-.. and |iii\i-iit thi` latter fioui being'deliriri-il to tliix iiiiwir.
